In the anomalous dispersion regime of fiber gratings, optical pulse can come into being bright solitons by a careful control of SPM、XPM and GVD, in the normal dispersion regime of fiber gratings can allowed transmission of dark solitons.
在光纤光栅中,当入射频率位于布拉格频率附近时,结构色散在系统中占主导地位,材料色散和波导色散等因素可忽略不计,在光纤光栅的反常色散区,由结构色散造成的群速度色散(GVD)效应和由自相位调制(SPM)、交叉相位调制引起的非线性效应的相互作用,可导致光纤光栅中亮孤子的形成;而在光纤光栅的正常色散区也能够维持暗孤子传输。
